1LOGO design says that official sites must use AI, but I basically use AI for printed materials, brochures and leaflets. PS is my auxiliary tool, but PS is used to preprocess special effects and various pictures appearing in flyers. Finally, it is all AI typesetting. Books and periodicals. It is ok to use AI, but my computer is generally too stuck. I am used to using indesign, and PS also assists indesign to complete book design and typesetting.
2 Electronic display advertisements on web pages, such as APP e-commerce design, I always use PS. Here, we need to pay attention to several factors: PS usually has a fixed e-commerce design resolution: 72-color mode: RGB, and the minimum font display is generally not less than 14 pixel.
Of course, PS can also be used for printing, the resolution must be 300, and the mode is cmyk. The minimum font size should not be less than 8 points as far as possible (note that the character unit is adjusted to "point"), so it is different for you to print with high precision with AI, and you can print with a font size of 3.9 points. Because it is a vector, PS can't do this.
3. It is recommended to use indesign or coreldraw for outdoor wall advertisements with inkjet photos, because these two softwares will not get stuck when encountering large-screen advertisements with good rice as the unit, and the computer can bear it. Ah ha ha
The above is purely personal experience.
